  • Door counterweight system
    Patent number: 5259433
    Abstract: An overhead door system employs counterweights which operate through cables connected to a drum which tapers from one end to the other so that the effective force acting on the door in the opening direction is reduced as the proportion of the weight of the door to be supported reduces. The system is adjustable readily to accommodate different types of doors having different opening characteristics in terms of the proportion of the doors weight that must be counterbalanced at different stages of the door opening movement. The drum has a pair of continuous grooves extending side-by-side throughout its length, the counterweight being independently supported by each of a pair of cables laid in these grooves.
